Mir was wildly overrated when people were trying to suggest he was one of the best HWs in the world (after his first win over Nog). That goes back to the MMA media's frustration with the state of the HW division (with most of the best HWs not in the UFC, which had almost all of the top fighters in every other division) as well as promotional propaganda. But I don't think that lasted too long. Mir opened at even odds against Nelson and closed as a slight favorite, which suggests that he was properly rated at that time. And obviously, after we saw the results of Mir vs. some of the guys I thought he'd lose to (Overeem, Barnett, and Cormier) and the success of guys like Werdum and AA, it's pretty clear in retrospect that Mir was a decent fighter but not one of the best HWs in the world. There are still some people who think that he's like a top-10 all-time HW, but I don't think that's a majority view or anything.
I did bet on Hunt, but not much. On the one hand, I didn't think Mir matched up well there, but on the other, I have very little confidence in Hunt against any decent fighter. Hunt was a slight favorite (-150 or something), which was appropriate.
